Another similarity between these three species is their horizontal canals that flank the jugal area fan out laterally opposed to straight.

The ENG tests the horizontal semicircular canal, which is innervated by the superior vestibular nerve.

The roll test can determine whether the horizontal semicircular canal is involved.

In particular the horizontal canal receives a rather dense afferent and efferent innervation in Brn3c null mutants.

The temperature difference between the body and the injected water creates a convective current in the endolymph of the nearby horizontal semicircular canal.

Absent reactive eye movement suggests vestibular weakness of the horizontal semicircular canal of the side being stimulated.

Ewald's second law: "Ampullopetal endolymphatic flow produces a stronger response than ampullofugal flow in the horizontal canal".

The lateral or horizontal canal (external semicircular canal) is the shortest of the three canals.

Studies have shown that the horizontal canal is most correlated with agility, as shown with several mammals.

The temperature gradient provokes the stimulation of the horizontal semicircular canal and the consequent nystagmus.
